Clinical and pathologic features of early gastric cancer in elderly patients

Background/Aims: The purpose of this study was to review the Clinicopathologic features of early gastric cancer in elderly patients. Methodology: Three hundred and seventy-two patients who underwent resection for early gastric cancer were divided into groups of patients younger and older than 70 years. The clinical and pathologic findings surgical treatment, and perioperative complications in the group of elderly patients with early gastric cancer were reviewed and compared to those of the younger group. Results: Gastric cancer involving the lower third of the stomach, as well as histopathologically well-differentiated carcinomas, were significantly more prevalent in the older group. Pre-operatively, the older patients had a higher incidence of respiratory dysfunction and hypertension. D1 lymph node dissections were chosen frequently for older patients. Six older patients died within 2 months of hospitalization, while no younger patients died within this period. The mortality rate mas 11% in older patients undergoing D2 or greater extents of node dissection, although the mortality rate was only 2% in older patients undergoing a D1 or less dissection. The 5-year survival rate for older patients, including deaths unrelated to cancer, was 71%, which was significantly lower than that in the younger group. However, when only mortality from gastric cancer was considered, patient survival did not differ according to age. Conclusion: Given the high mortality in elderly patients unrelated to early gastric cancer, we concluded that node dissection should be limited to perigastric nodes according to tumor location in such patients.
